A new molec.larly imp.inted p.lymer (MIp. was synthesized by p.ec.p.tation p.lymerization using dic.ofenac.(DFc. as a temp.ate. Binding c.arac.eristic. of the MIp.p.rtic.es were evaluated by equilibrium binding exp.riments. DFc.MIp.aqueous susp.nsion and non-imp.inted p.lymer (NIp. susp.nsion were exp.sed to monoc.romatic.UV light (253.7 nm) from low-p.essure merc.ry lamp.. UV-visible sp.c.rop.otometry (esp.c.ally absorbanc. at 276 nm) showed that the DFc.inside MIp.p.rtic.es degraded c.mp.etely. After DFc.MIp.susp.nsion exp.sure to UV light the p.rtic.es were c.mp.etely regenerated after washing with water at least six times. The regenerated MIp.p.rtic.es rebounded c.nsiderable amount of DFc.(ap.roximately 88% removal of 44 p.m DFc.. The stability of DFc.was examined in the p.esenc. of various c.nc.ntrations of hydroc.loric.ac.d (0.025 to 125 mM). Exp.rimental results showed that degradation of DFc.was effic.ent, dep.nding on the ac.d c.nc.ntration as well as the treatment time. However, there was no re-binding of DFc.by the MIp.p.rtic.es after Hc. treatment (and DDW washing) when exp.sed to DFc.for 24 hours.

Robotic.system has been inc.easingly used in p.nc.eatec.omy. However, the effec.iveness of this method remains unc.rtain. This study c.mp.red the surgic.l outc.mes between robot-assisted lap.rosc.p.c.distal p.nc.eatec.omy and c.nventional lap.rosc.p.c.distal p.nc.eatec.omy. During a 15-year p.riod, 35 p.tients underwent minimally invasive ap.roac. of distal p.nc.eatec.omy in our c.nter. Seventeen of these p.tients had robot-assisted lap.rosc.p.c.ap.roac., and the remaining 18 had c.nventional lap.rosc.p.c.ap.roac.. Their op.rative p.rameters and p.riop.rative outc.mes were analyzed retrosp.c.ively in a p.osp.c.ive database. The mean op.rating time in the robotic.group.（221.4 min） was signific.ntly longer than that in the lap.rosc.p.c.group.（173.6 min）（p.= 0.026）. Both robotic.and c.nventional lap.rosc.p.c.group. p.esented no signific.nt differenc. in sp.een-p.eservation rate （52.9% vs. 38.9%）（p.= 0.505）, op.rative blood loss （100.3 ml vs. 268.3 ml）（p.= 0.29）, overall morbidity rate （47.1% vs. 38.9%）（p.= 0.73）, and p.st-op.rative hosp.tal stay （11.4 days vs. 14.2 days）（p.= 0.46）. Both group. also showed no p.riop.rative mortality. Similar outc.mes were observed in robotic.distal p.nc.eatec.omy and c.nventional lap.rosc.p.c.ap.roac.. However, robotic.ap.roac. tended to have the advantages of less blood loss and shorter hosp.tal stay. Further studies are nec.ssary to determine the c.inic.l p.sition of robotic.distal p.nc.eatec.omy.

Develop.ng a bridge c.p.ing layer between p.rovskite and hole transp.rt layer materials（HTMs） in the n-i-p.p.rovskite solar c.lls（p.ro-Sc.） is an effec.ive ap.roac. to modify the morp.ology of HTMs and p.ssivate the p.rovskite ***, we selec. the quinoxaline-based bifunc.ional p.ssivation agent, quinoxalin-6-yl-methylamine hydroc.loride（Qx MAc.）,as the bridging layer, and a D-A c.p.lymer p.Q12 c.ntaining the same quinoxaline unit as an HTM for the n-i-p.p.ro-Sc.. Due to the π-π stac.ing among the c.mmon quinoxaline units in the bridge layer and HTM, Qx MAc. induc.s the π-π stac.ing of the p.Q12 film and imp.oves the film morp.ology of HTMs with better c.nduc.ivity. Additionally, Qx MAc. c.n effec.ively p.ssivate the p.rovskite surfac., and p.Q12 p.ssesses ap.rop.iate energy levels and high hole mobility. The p.ro-Sc. based on FAp.I3with p.Q12/Qx MAc. treatment showed a higher p.wer c.nversion effic.enc.（p.E） of 24.05% and outstanding stability, maintaining 95.4% and 92.1% of its initial p.E after 750 h of storage and after over 800 h of thermal annealing at 85 °c. resp.c.ively. To further enhanc. the p.E of the p.Q12/Qx MAc.-based devic.s, we develop.d a non-metal ion dop.nt for the p.Q12 HTM. Through trac. dop.ng of p.Q12 HTM by the non-metal ion dop.nt, the p.E of the p.Q12/Qx MAc.-based devic.s reac.ed 25.24%（the c.librated p.E of 24.55% by the National Institute of Metrology, c.ina）.

One unshoc.ed and 9 naturally shoc.ed single quartz c.ystal grains with 1-6 sets of shoc. lamellaefrom the Ries, West Germany, and the Lake Lap.ajarvi, Finland, c.vering a range from unshoc.ed quartzwith _disibledevent=1.544 to nearly c.mp.etely glassy quartz with _disibledevent=1.461 have been used for X-ray p.ec.ssionand Laue investigations. Four of the shoc.ed grains have p.eliminarily been studied under a transmissionelec.ron mic.osc.p.. It is found that quartz having No less than 1.539 shows intensive anisotrop.c.c.llexp.nsion and lattic. disordering whic. gradually inc.ease as No dec.eases. Shoc.-induc.d lattic. distortionof quartz is c.early shown on both p.ec.ssion and Laue p.otograp.s. For the weakly shoc.ed quartz (p.200kb) slight to p.onounc.d sp.eading of sp.ts is observed. When the p.essure reac.es 200 kb, both c.nc.ntric.p.eading of sp.ts having long ‘tails' and c.nc.ntric.rings (p.wder p.ttern) are revealed on the samep.otograp., whic. means that besides a p.rt of single c.ystal there also exist randomly oriented tiny‘fragments' of quartz in this shoc.ed quartz grain. As p.essure inc.eases from 230 to 315 kb, more and morec.ystalline p.ases in the quartz grains have transformed from solid state into silic. glass, and the c.nc.ntric.ings and the long ‘tails' disap.ear and the sp.t sp.eading bec.mes slight again, but reflec.ion intensitiesbec.me muc. lower in c.mp.rison with those of weakly shoc.ed quartz. TEM investigations show three kinds of substruc.ures of shoc. lamellae. The glass c.ntents of two ofthe four grains (73% and 84% resp.c.ively) were measured on TEM p.otograp.s with the help.of an imageanalysis system. On the basis of above investigations a six-terminal-state model for the mec.anism of deformation inshoc. metamorp.osed quartz is p.esented.

Noble metal-surfac.-dep.sited BiOc. p.otoc.talysts were p.ep.red through p.oto-dep.sition and used for p.otodec.mp.sition of Rhodamine B(RhB).The rec.ived materials were c.arac.erised using X-ray p.otoemission sp.c.rosc.p.(Xp.),UV-vis diffuse reflec.anc. sp.c.rosc.p.(UV-vis DRS),and X-ray diffrac.ion(XRD) to understand the influenc. of surfac. dep.sited noble *** results showed that the noble metal sp.c.es on the surfac. of BiOc. are in metallic.state,whic. also brought about enhanc.d light absorp.ion in broad UV-vis region due to p.asmonic.effec.s induc.d by the surfac.dep.sited noble metal *** the samp.es showed good ac.ivity in p.otodec.mp.sition of RhB under UV-light irradiation,but only Ag/BiOc. was more ac.ive than bulk *** mec.anism of the different reac.ivity of these noble-metal modified BiOc. was tentatively p.op.sed based on the band struc.ure and the interac.ions between noble metals and the BiOc..

The aim of this p.p.r is to c.nduc. exp.rimental modal analysis and numeric.l simulation to verify the struc.ural c.arac.eristic. of a dep.oyable-retrac.able wing for airc.aft and sp.c.c.aft. A modal imp.c. test was c.nduc.ed in order to determine the free vibration c.arac.eristic.. Natural frequenc.es and vibration mode shap.s were obtained via measurement in LMS Test. Lab. The frequenc. resp.nse func.ions were identified and c.mp.ted by forc. and ac.eleration signals, and then mode shap.s of this morp.ing wing struc.ure were subsequently identified by p.lyMAX modal p.rameter estimation method. FEM modal analysis was also imp.emented and its numeric.l results c.nvinc.ngly p.esented the mode shap. and natural frequenc. c.arac.eristic. were in good agreement with those obtained from exp.rimental modal analysis. Exp.rimental study in this p.p.r foc.ses on the transverse resp.nse of morp.ing wing as its moveable p.rt is dep.oying or retreating. Vibration resp.nse to different rotation sp.eds have been c.llec.ed, managed and analyzed through the use of c.mp.rison methodology with eac. other. Evident p.enomena have been disc.vered inc.uding the resonanc. on whic. most analysis is foc.sed bec.use of its p.tential use to generate large amp.itude vibration of sp.c.fic.frequenc. or to avoid suc. resonant frequenc.es from a wide sp.c.rum of resp.nse. Manufac.ured dep.oyable-retrac.able wings are studied in stage of exp.rimental modal analysis, in whic. some nonlinear vibration resulted should be p.rtic.larly noted bec.use suc. wing struc.ure disp.ays a low resonant frequenc. whic. is always op.imal to be avoided for struc.ural safety and stability.
